Opto-isolator devices are used for electrical isolation between circuits to avoid interference. PC814XP is a type of Transistor-Photovoltaic Output Optoisolators. Not only does it protect the input side from the output side, it also allows for a wide range of illumination control levels and power distribution. It is an ideal choice for automotive, industrial, and consumer applications.

The PC814XP opto-isolator uses a light-activated transistor with a four-lead package. It works by using an LED on the input side, which is aimed at a phototransistor on the output side. When the LED in the input section sends a signal, the phototransistor in the output side switches on or off. This action isolates both input and output stages, protecting the rest of the circuit.

In spite of its small size, the PC814XP offers great performance parameters. It has a CTR ratio of 40% to 600%, an operating temperature of -40 °C to 85 °C, a maximum collector-emitter voltage of 30V, and a fast switching response of about 5 microsecond. The maximum current through the input and output stages is at 30mA. It is UL approved and supports Pb-free terminations.

The PC814XP Transistor-Photovoltaic Output Optoisolator offers superior noise immunity, which is essential for high-frequency or sensitive data transmission in noise-sensitive systems. Its space-saving four-lead mini-flats package allows for easy mounting on a printed circuit board. It provides reliable electrical and optical insulation in the mentioned applications such as medical equipment, factory automation equipment, and home appliances.

The PC814XP opto-isolator has various application fields which includes, but is not limited to: measuring instruments, electronic apparatus, industrial automation systems, switching circuits, digital logic circuits, etc. In all these scenarios, its working principle remains the same. The output voltage is controlled by varying the input voltage of the LED. If the input voltage is increased, the current will increase too, and the light intensity and output voltage will increase as well.

PC814XP Transistor-Photovoltaic Output Optoisolators offer benefits such as isolation voltage up to 5000Vrms, noise immunity, wide operating temperature ranges, and superior electrical and optical insulation. All these advantages make it an ideal choice for automotive, industrial, and consumer applications. It is a reliable and effective device designed to provide electrical isolation between circuits and protect rest of the system from interference.
